Alphacool Brass HardTube 13 mm 90°

The Alphacool Brass HardTube is a pre-bent chrome-plated brass tube for custom water-cooling loops. It has a 13 mm outer diameter and a 12.2 mm inner diameter with a .8 mm wall thickness. One leg measures 30 cm and the other 10 cm, forming a 90 degree angle. The durable chrome finish resists scratches under normal handling.

Builders planning tight 90° routing

This tubing suits builders who need a precise right-angle turn without heating and bending straight tube themselves. The fixed 10 cm and 30 cm leg lengths limit flexibility, so loops requiring different dimensions or multiple bends should use straight HardTube instead. Cut ends must be deburred with fine sandpaper or a dedicated tool to protect fitting O-rings.

Fixed-length right-angle section

The pair provides a single 90 degree corner with 30 cm and 10 cm straight runs, covering many motherboard-to-radiator or GPU-to-distribution-plate paths. Loops needing longer reaches, additional bends, or non-right angles will require extra straight tubing and fittings. The 100 g weight adds negligible mass to the loop.

Questions about this item

What fittings do I need for the 13 mm outer diameter brass tube?

Use compression fittings rated for 13 mm OD tubing with an inner diameter of 12.2 mm; the 0.8 mm wall thickness means standard hard-tube fittings will seal correctly.

Will the 90° bend fit alongside my existing straight 13 mm hard tubes?

Yes — the bend shares the same 13 mm OD and 12.2 mm ID as straight Alphacool HardTubes, so it connects to identical fittings without adapters.

How can I verify the chrome finish is intact after cutting and deburring the 10 cm and 30 cm legs?

Inspect both cut ends under bright light; the plating should show no exposed brass, and a finger-tight fitting should seat without resistance or visible scratches.
